Given numbers are 487,620,478,263

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 487,620,478,263 is 18979042580.

Find LCM of 487,620,478,263 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 487 x 310 x 239 x 263 = 18979042580

Therefore, the lowest common multiple of 487,620,478,263 is 18979042580.

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

487 x 620 x 478 x 263 = 37958085160

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

487 : 1, 487

620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620

478 : 1, 2, 239, 478

263 : 1, 263

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 487,620,478,263, is 1.

Now, the common factors can be found like this.

487:487

620:2x 2x 5x 31

478:2x 239

263:263

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2 = 2

Therefore, the value for common factors is 2.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 37958085160/(1x2)

LCM = 37958085160/2

LCM = 18979042580

Thus, we can understand that the LCM of 487,620,478,263 is 18979042580.
